VALVE FOR PROCESSING APPARATUS.

SPECIFICAQION forming part of Letters Patent No. 777,776, dated December 20, 1904.

Application filed July 3,1903. Serial No. 164,122.

To Ml 14172 0177 it 777.11 concern:

Be it known that I, ROBERT E. lanolin, a citizen of the United States, residing at Greenwood, in the county of Johnson and State of Indiana, have invented certain new and useful lnn'n'ovenients in Valves for Processing Apparatus, of which the following is a specification.

This invention relates to a combined valve and rotary convcyer for introducing and discharging canned goods from processing apparatuscs, and is particularly adapted to be employed in connection with such an apparatus that forms the subject-matter of an application for patent now pending on apparatuses for steaming and processing canned goods filed byJohn Jennings on September 13, 1902, and allowed May 9, 1903 Serial No. 123,283. The receiving and discharging apertures of the processing apparatus are both provided with such a device comprising a rotary conveyor and a plurality of yieldable valve-wings that ride on the periphery of the rotary conveyers and prevent the escapeinent oi the steam from the interior of the apparatus.

A device embodying the various features of my invention will first be fully described and then pointed out in the claims.

ltaierring to the accompanying drawings, wl irh are made a part hereof, and on which similar numerals of reference indicate similar Figure 1 is a top or plan view of the nch incloses the combined valve and rotary conveyor. 2 is a horizontal central sectional view 01 the construction shown in Fig. 3. Fig. 3isa horizontal sectional view on tho 1 mod line 3 3 in Fig. i. Fig. L is a ci ation of the construction shown in Fig. 5 isa cross-sectional view of the .on the line 5 in Fig.2. Fig. 6 is a oi the construction shown in Fig. a perspective view of the door 'ch incloses the conveyor and i .on the int.

drawings, 1 is the rotary conveyor with a series oi? can-carrying pocle pockets extend longitudinaliv n and are of a less degree of le.

able casing 10. which is secured to the wall .25

of the processing apparatus. The casing 10 is provided witha i'ioor 11. which is provided with the jut or projection 12, over which the cans are discharged.

The conveyor 1 has rotary movement and is provided with the can-carrying pockets 7, which receive the cans and carry them into or out of the processing apparatus. The cans under the impulse of the conveyor are slid over the floor 11 until they reach the int 12. when they are discharged from said floor upon the movable floor in the processing apparatus. The movement of the last-mulled floor with. draws the cans from the pOCliUtS T in the conveyer 1.

suitable delivering dcvicc 15 delivers the cans upon the floor 11 ot' the casing 10 and upon such delivery the cans are immediately removed by the conveyor 1 and are thence discharged into the processing apparatus.

Diiiieulty was experienced in introduciiig or discharging the cans from the apparatus by escaping steam. The steam is under pressure inside the apparatus and it escaped. in such a volume at the points of introducing and removing the cans as to envelop the apparatus. The escaping steam seriously interfered with the operator in charge of the apparatus. To overcome this obstacle, i provide the rotary conveyer 1 and a series of Wings 20, which act as valves. lhese wings are pivot-ally secured to the casing 10 at 21 and ride on the periphery of the conveyor. The wings 20 extend h'ingitudinally the entire length of the conveyor 1 and circuniferentially a distance suiiicient to embrace one or more of the walls 3. that form the pockets in the conveyor 1. The face of the wing. 21') are made to conform with the periphery of the conveyer and are held into contact therewith by suitable tension devices 22. It will be seen by examining Fig. 2 that the wings 20 are arranged relatively to the conveyer 1, that as the walls 3 pass-from under the ends of the wings the succeeding walls have previously engaged them. This construction seals the openings between the casing 10 and the conveyer 1.

Having thus fully described my said invention, what I desire to secure by Letters Patent is 1. In a can receiving and discharging device comprising a rotary conveyer provided with a series of pockets which are ofless length than the conveyer, a casing inclosing the conveyer and provided with a can-receiving aperture, means movably secured to the casing andadapted to ride on the periphery of the conveyer, and means suitably arranged to operate the conveyer.

2. In a can receiving and dischargingdevice comprising a rotary. conveyer provided with i aserles of pockets, suitable means for operating the conveyer, a casing for inclosing the conveyer, a floor provided for the casing, a

jut formed in the floor for eflecting the discharge of the cans from the conveyer, a plurality of Wings movably secured to the casing and adapted to ride on and to embrace one or more of the pockets in the conveyer.

3. In a can, receiving and dischargingdevice comprising a rotary conveyer provided with a series of pockets, suitable means for operating the conveyer, a casing inclosing the conveyer and provided with a can-receiving aperture, a floor provided for the casing, means in the floor for etfecting the discharge of the cans from the conveyer, a plurality of wings movably secured and arranged relative to the conveyer to ride on the periphery thereof and embracing one or more of the walls that form the pockets, and means suitably arranged for holding the Wings into contact with'the conveyer. s I

4. In aprocessing apparatus, the combination with the frame, a can receiving and discharging device comprising a rotary conveyer provided with a series of pockets, means for operating the conveyer, a casing inclosing the conveyer, a floor provided for the casing, jut in the floor for effecting the discharge of the cans from the conveyer, means movably secured and adapted to ride on the periphery. of theconveyer for sealing the openings between the casing and conveyer.

In witness whereof I have hereunto set my hand and seal, at Indianapolis, 30th day of June, A. D. 1903.
